Mycorrhiza is a symbiotic association between a group of soil fungi called arbuscular mycorrhizal fungi and plants. The successful association between plants and AMF constitutes a strategy to improve the nutritional status of both associates, which reduces the use of fertilizers specially phosphorus nutrition (Almagrabi and Abdelmoneim, 2012). The AMF take carbohydrates compounds from their pla...

Considering the persistently growing pressure on finite freshwater and soil resources, it becomes increasingly clear that the challenge of feeding tomorrow’s world population is, to a large extent, about improved water productivity within present land use. Rain-fed agriculture plays a critical role in this respect. Eighty per cent of the agricultural land worldwide is under rain-fed agriculture...

A comprehensive assessment of drought environmental and socio-economic impacts provides critical information to rational decisions supporting drought mitigation policies and programs. The objectives of this study were to survey environmental and socio-economic impacts of drought in Guilan Province, and prioritize them from the viewpoint of paddy farmers.

In the structure of the Integral Irrigation Advisory Service (Servicio Integral de Asesoramiento al Regante, SIAR) of Castilla-La Mancha, with the principal objective of helping farmers to get a efficient and rational use of means of production, and specially water, fertilizers and energy, providing a suit scientific and technical support to optimise management, it is fundamental to broach the ...

Water shortage in the arid-semiarid regions of China seriously hampers ecosystem construction. Therefore, elucidation of the mechanisms by which vegetation in that area responds to drought stress may enable us to improve utilization of limited water resources and thus contend with the problem of drought and water shortage. We studied Bothriochloa ischaemum, a native grass species, conducted pot...

Background: New sources of hydroclimate information based on forecast models and observational data have the potential to greatly improve the management of water resources in semi-arid regions prone to drought. Better management of climate-related risks and opportunities requires both new methods to develop forecasts of drought indicators and river flow, as well as better strategies to incorpor...
